"Essentially this is a solution in search of a problem. I mean, somebody had an idea - 'Let's make the controller a tablet' - and there aren't many games that are going to take advantage of that," explained Pachter at last week's Develop Conference.

"Activision never said anything to me, but I know that [for] big games like Call of Duty they said, 'No, we're not putting it on there if you don't give us a conventional controller'. So they gave in."

Suggesting that Nintendo got lucky with the Wii, Pachter went on to say: "It worked, they got lucky [but] I don't think they're getting lucky with the Wii U.

"They really believe that, 'If we're still novel, everything we do will work'. This isn't going to work."
